After updating to this driver I've had some issues:
First off, I noticed I could enable VBO without getting the pointy things trying to reach through the screen and jab my eyeballs out. So kinda cool that ATI is fixing that, but, it also slowed my display down to 3 or 4 fps. So, VBO remains off. Other than that, I now have a jumpiness when in motion that wasn't there before... hesitations that when flying makes me overshoot my target often. I also see classic clouds with a diamond tuck and roll pattern. Tied with that is textures underwater disappear (go gray) when my cam goes underwater. If I disable atmospherics, I get them back, but the look is rather flat, then. This happens in both SL Viewer and Emerald. Guess I will be rolling back to earlier driver, unless someone here knows something.
System Specs:
Vista 64
i7-965 @3.2Ghz
12 GB RAM
2 x ATI Radeon HD4870x2 (I tried CrossFire and didn't notice an improvement for Sl so mostly off)
(UPDATE)
Sorry, I just saw this has been reported already - please ignore.
